September 3rd
David Wang and myself lowered the leak testing cart into the Ante room and prepared the ante-room for the leak testing of TM3s line. David and
Grant then entered the anteroom and inspected the old c-seal and leak tested the the heat shield line. The line pumped down to the lower limits of the |

Today Maico measured the thickness of three indium-plated inconel c-seals, presumably Ultra-Seal P/N 50606. These seals had NOT been in the Hot
Cell.

|
Yesterday, Grant entered the Ante Room with David Wang to visually inspect the two sets of failed c-seals from the Heat Shield circuit, to remove the
second set from the Heat Shield water blocks, and to leak check the heat shield circuit with o-rings and a water-block-to-leak-detector fitting.
Some photos of the inspected seals are in the attached design review presentation. Some unusual marks were observed on both sets of failed |

|
Today Maico completed the new leak testing tool and blank off. He tested them with C-seals without springs and all was leak tight. He then inspected
the crushed seals and noticed that there was an area that was crushed less on both seals (more prominent in one, 20130906_tm3sourtrayefurb_P1020975)
and that this reduced crushed zone only appears on one side of the seal. This is similar to the failure seen on both sets of the heat shield lines. On |

The sealing surfaces of the module side heat shield water block were polished on September 9th in the morning using Chad's polishing tool with
the following attachments:
- Scotchbrite pads (30 seconds) (after this step indium material from the previous seal was no longer visible on the sealing surface) |

|
I leak checked TM3 water lines at CS with 60 psi and 80psi helium. The base leak rate is 5.0xe-9 atm.cc/sec. Each circuit 3 minutes helium pressurizing
for each time test. No any respose had been found on leak detector during the test. See attachment |

Leak checked TM4 coil1 in SHC with Isaac . The leak detector only can pump down to 1.5xE-7 atm.cc/sec. The leak detector got the response once the helium
valve is open, not even close to the leak area. The leak detector got a very big response when the helium probe was put close to the coil terminal block
on target front side and spray helium for 2 clicks. The leak detector got a small response when the probe was put close to water block area and spray |

The wiring harness was completed by Maico and Travis today (see pics) and was installed into the target module. During installation the bracket
went on with ease. The junction box appeared to be hung up on something but did engage eventually. The plug for the collimator is not quite long enough |

This morning, Bevan and I leak checked window circuit on TM3 at SHC after containment box was installed. It took about 20minutes to pump down the circuit
to 0.0xE-9atm.cc/sec. Bevan sprayed helium on both VCR joints and a final splash. No response had been found on leak detector. |

happens the seal becomes stuck at the bottom of the containment box. While trying to replace the seal the nut slipped down the line to the bottom of |

Today Maico and Travis completed and electrical test to determine the right and left coil on TM4. The left coil is the negative side. From there
Maico pumped on both lines for a leak test. The leak cart pumped down to its lower limits on the left line and there was no response when sprayed with
helium. The right line would not pump below 2.5 x 10^-2 Torr and had a base leak rate of 3.3 x 10^-7 atm*cc/sec (this indicates a massive leak). Without |
